AIR-CONDITIONING AI 'PARATUS.

' Application filed January 8, 1924. Serial Io. 685,071.

To all whom it may concern Be it known that I, KARL G. RUNBACK, a subject of the King of Sweden, residing at New York, in the county and State of New York, have invented certain new and useful Improvements in Air-Conditioning Apparatus, of which the following is a specification. I

Thisinvention relates to an air-conditioning apparatus comprising an air filter arranged in a horizontal or inclined position, from which filter particles of oil or other liquid, or solidparticles. may become detached and drop down. The invention relates specifically to the provision of means for collecting such liquid or solid particles as may fall from the filter, such means comprising a receptacle or series of receptacles adapted tobe slidably or otherwise detachabllyh secured beneath the filter.

. y e principal advantage derived fro the invention is, that it revents any particles which become detac ed from the filter from falling into any machinery beneath it, such, for instance, as a heater arranged close to a filter of the so-called semi-d'rv type, in which a filter medium coated with an oily liquid is used which changes its viscosity wlth the tem rature. I

Other advantages Wlll. be apparent from the followin specification taken in'connection with t e accompanying drawing in which:

Fi re 1 isa vertical sectional. view' of the lter and the receptacle;

Fig. 2 is a similar view showing another. means of attaching the receptacle;

Fig. 3 isa plan view of the filter and the receptacle;

Fig. 4 is a vertical section of a filter comblned with a series of receptacles and a heater;and

Fig. 5 is a side view of the receptacle and its supports.

Throughout the several figures of the drawing, 1 indicates the filter which is of any desired type or construction and can also be removably or otherwise secured in place, depending upon the specific service required. This filter is provided with a receptacle 2 having a bottom portion 11 and sides 12, which latter are bent at right angles to the bottom portion. The receptacle is secured in place by means of hinged supports 3 and rigid supports 4. These supports may also consist of a single support,-in which case suitable openings are provided to allow for circulation of air. The'hiuged support has a bent portion l3adapted to engage with the bottom 11 of the "receptacle, and the rigid support 4 hasa suitable opening 14 at the lower. end into which a hook 15' is adapted to engage, saidhook being secured to the side 12 of the receptacle,

It will thus be apparent that the receptacle can be removed by merely swinging back the support 3 and unhooking it from support 4. The receptacle may also be attached beneath the filter so that it can be slidably removed, as shown in -Fi 2 wherein the receptacle 2"is illustrate as suspended by the supports 6 by means of bent portions 16. The supports are designed in this way in order that the receptacle may be removed for cleaning or other purposes.

Since all of these supports 3, 4 and 6 are arranged at suitable intervals, the air will pass through the filter and past said supports, as indicated by the arrows. 'Thus. 80 any material falling from the-filter will dro directly into the receptacle and will not fa on any machinery, etc., which may be under it.

In Fig. 4, a filter 1 is shown as mounted in a casing 17, and under this filter a series of receptacles 8 is suitably mounted; but it is to be understood that a single receptacle could be substituted for this series. The receptacles 8 are shown arranged in two rows, the bottom row being arranged to overlap each two receptacles of the upper row. Thus passages are provided between the receptacle of the rows and between the rows as indicated by arrows in Fig. 4. Under the series of receptacles, a heating arrangement is provided in the casing for heating'the air entering the casing 17 at inlet 18. This heating arrangementls shown as a coil 10 heated by any suitable means. The air to be cleaned enters through inlet 18, then passes through the coil 10 which is heated, passes between the rece tacles, and then through the filter, as in icated by the arrows.' Any particles, either liquid or solid, which may become detached from the filter will fall on one of the receptacles and thus will not. fall on the coil 10 or other a paratus that may be located under the her.

The devices under the filter tocatch any particles falling therefrom are especially advantageous when an oily filter medium viscosity due to the heating of the air by coil 10, which would cause the said medium to more easily drop from the filter.

I claim as my invention 1. In an air conditioning apparatus, a fil 'ter; a plurality of hinged su ports; a plurality of fixed supports; an a receptacle associated, with Sfild supports positioned under and adapted to receive particles falling from said filter, said receptacle being removably secured by means of said hinged supports.

2. In an air conditioning apparatus, a filter; and a plurality of receptacles arranged in groups so that assages will be formed betweenthe indivi ual receptacles and said filter, and the individual receptacles of a group overlapthe receptacles below.

3. In an air conditioning apparatus, a filter; a receptacle associated with and located beneath said filter to receive particles falling therefrom; and means for heating the air passing through said filter, said means being arranged beneath said receptacle to protect it from said filter.

4. In an air conditioning apparatus, a filter; a receptacle comprising a bottom portion and side portions; hooks on one of said 1 side portions; a lurality of hinged supports, each provi ed with a bent portion; and a plurality of rigid supports each provided with an openin for receiving said hooks, said receptacleie secured beneath the filter by means of said supports to receive particles falling from said filter.

5. An air conditioning apparatus comprising a casing; a filter secured in said casing; a plurality of rece tacles arran ed in said casing beneath sai filter and a a ted to receive particles fallin from said ter; and means in said casing or heating the air passing through the apparatus, said means being arranged beneath. said receptacle to protect it from said filter.

In testimony whereof I afix my signature.
